FireCalc Pro –AS Fire Standard

About FireCalc Pro –AS Fire Standard

FireCalc Pro is the professional hydraulic design tool for fire protection engineers, hydraulic consultants, and building certifiers calculating town main fire sprinkler systems to Australian standards.

⚡ INSTANT HYDRAULIC CALCULATION
Enter your hazard class, pipe sizes, and site data — FireCalc Pro calculates the complete pressure loss budget and duty point in real time:

✔ Total design flow — N × q × 1.12 (AS 2118.1 Cl. 5.2 multiplier applied automatically)
✔ Static head loss (height above town main connection)
✔ Hazen-Williams friction loss — GF main line, riser, and topmost floor pipework
✔ BFP (Backflow Prevention Valve) pressure loss — DN65, DN80, DN100, DN150, DN200
✔ SCV (Sprinkler Control Valve) equivalent-length friction loss
✔ Residual pressure at most unfavourable head
✔ Combined sprinkler + hydrant duty flow
✔ Water storage tank sizing — run time × buffer per selected standard

🔥 ALL HAZARD CLASSIFICATIONS
LH Resi · LH E.C Resi · LH Std · OH1 · OH1 E.C · OH2 · OH2 E.C · OH3 · OH3 E.C · OH3 Special · OH3 Special E.C · High Hazard Process (density × area) · High Hazard Storage (K-factor: Q = N × K × √P)

📐 MULTIPLE DESIGN STANDARDS
Instantly switch between:
• AS 2118.1 — General building sprinklers, town main (×1.12 multiplier, ×1.2 tank buffer)
• AS 2118.4 — Residential & domestic (×1.00, 30 min fixed run)
• FPAA 101H — Hydrant-fed residential (×1.00, 30 min, 70 kPa min)
• FPAA 101D — Domestic mains supply (×1.00, 10 min, 50 kPa min)

Each standard automatically applies its design multiplier, tank buffer, run time, and minimum operating pressure.

💧 HYDRANT FLOW TEST ANALYSIS
Record field hydrant flow test readings and plot supply curves. FireCalc Pro linearly interpolates available pressure at your exact duty flow and gives an instant ADEQUATE / DEFICIENT verdict with the pressure margin.
